* Chromium VI: This means chromium in its +6 oxidation state, which is written as Cr(VI).
* Sulfate: This is the polyatomic ion SO₄⁻², which has a -2 charge.
Since we need to balance the charges, we need to figure out how many chromium ions and sulfate ions we need.
* To balance the +6 charge of the chromium, we need three sulfate ions (3 x -2 = -6).
* To balance the -6 charge of the sulfate ions, we need two chromium ions (2 x +3 = +6).
Therefore, the formula for chromium VI sulfate is Cr₂(SO₄)₃.
